Abstract
A cable system in which a plurality of non-interactive channels occupy a first group of carrier frequencies and a plurality of pseudo-channels, each assigned to an information service from a plurality of information services, are carried by a second group of carrier frequencies. A tuner is controlled by a processor in response to a channel selector. If the selected channel number represents a non-interactive channel the tuner is set to that channel. If the selected channel number is a pseudo-channel representing an interactive service, the tuner is set to an assigned carrier frequency in the second group of carrier frequencies. The assigned carrier frequency is provided from a cable control mode to a data receiver at the subscriber's television interface controller. Channels are selected from a single numerical sequence of channel numbers.
